Customer restriction

Responsibility Diffusion

A platform controls discovery, pricing, payment and rules, and earns revenue on each transaction, while contractually positioning itself as a non-party to that transaction and distributing operational responsibility for failure across third parties — retaining discretion over remedies without corresponding liability.

Why it matters

The customer buys from the platform and, when it fails, discovers they did not.

Marketplace platforms sit between two parties and increasingly control every layer that determines whether a transaction succeeds: what the customer sees, what they pay, how they pay it, who is allowed to participate, what the rules are, and who is believed when something goes wrong.

Responsibility Diffusion appears when the same platform, having centralised all of that, locates the legal obligation for the transaction's performance entirely in the counterparties — and then administers whatever remedy exists at its own discretion.

How it works

The mechanism is contractual rather than operational. Terms of service state that the platform is not a party to the underlying agreement, does not own or control what is sold, and administers its policies at its sole discretion. Customer protections are then offered as programmes rather than contractual entitlements: branded as guarantees, delivered as discretionary decisions, and typically bounded by a reporting window, an evidence requirement and a severity assessment the platform performs itself.

The result is an asymmetry that only becomes visible during failure. In the ordinary case, the platform behaves exactly like the seller. In the failure case, it becomes an intermediary again — and the customer is directed first to the counterparty, then to a support function, then, in many jurisdictions, to individual arbitration.

CHI distinguishes this sharply from poor customer service. Slow support is an execution problem. Responsibility Diffusion is a structural allocation: revenue centralised, accountability distributed, discretion retained.

Recognition checklist

What to look for

The platform controls the transaction

Discovery and ranking, price presentation, payment, identity, the rulebook, dispute adjudication and enforcement all sit with the intermediary.

It earns a percentage of it

Revenue is taken from each transaction, whether charged to the buyer, the seller, or built into the displayed price.

It disclaims party status

The terms state that the contract runs between the counterparties, that the platform does not control them, and that its policies are administered at its discretion.

Remedy is a programme, not an entitlement

Protections are branded as guarantees but bounded by reporting windows, evidence standards and severity assessments the platform performs itself.

Correction depends on escalation

Documented failures are reversed after persistence, press attention or public visibility rather than at first instance — a mechanism CHI records as publicity-gated remedy.

Where it appears

Associated companies

Airbnb — type specimenHighRide-hailing platformsCandidateFood-delivery platformsCandidateOnline marketplaces with third-party sellersCandidate

Airbnb is the entry's type specimen because its Terms of Service state the position most plainly — "Airbnb is not a party to the contracts entered into directly between Hosts and Guests," alongside policies administered "at its sole discretion" — while the platform controls ranking, price display, payment, identity verification, the house-rule structure, review adjudication, refunds and account enforcement, and takes roughly 13.5% of gross booking value. The adjacent candidates are listed as candidates: no CHI investigation has yet assessed them against this definition.

Important distinction

Intermediation is not the harm. Asymmetry is.

Marketplaces are legitimate, and a platform is not obliged to underwrite every transaction on it. Nor does the existence of a protection programme make one hostile — a free, universal guarantee is real customer value, and CHI scores it as such.

The relevant questions are narrower. Does the platform's control of the transaction match the responsibility it accepts for it? Is the remedy enforceable by the customer, or decided about them? Are the boundaries — windows, evidence standards, exclusions — disclosed as clearly as the guarantee is marketed? And does correction depend on process, or on publicity?
